obj.fire('test', 'This is the message');
Test if there are any handlers bound to an event name.
The name of the event to test.
True if the object has handlers bound to the specified event name.
obj.on('test', function () { }); // bind an event to 'test'
obj.hasEvent('test'); // returns true
obj.hasEvent('hello'); // returns false
Detach an event handler from an event. If callback is not provided then all callbacks are unbound from the event, if scope is not provided then all events with the callback will be unbound.
Optional
name: stringName of the event to unbind.
Optional
callback: HandleEventCallbackFunction to be unbound.
Optional
scope: objectScope that was used as the this when the event is fired.
Self for chaining.
const handler = function () {
};
obj.on('test', handler);
obj.off(); // Removes all events
obj.off('test'); // Removes all events called 'test'
obj.off('test', handler); // Removes all handler functions, called 'test'
obj.off('test', handler, this); // Removes all handler functions, called 'test' with scope this
Attach an event handler to an event.
Name of the event to bind the callback to.
Function that is called when event is fired. Note the callback is limited to 8 arguments.
Optional
scope: object = ...Object to use as 'this' when the event is fired, defaults to current this.
Can be used for removing event in the future.
obj.on('test', function (a, b) {
console.log(a + b);
});
obj.fire('test', 1, 2); // prints 3 to the console
const evt = obj.on('test', function (a, b) {
console.log(a + b);
});
// some time later
evt.off();
Attach an event handler to an event. This handler will be removed after being fired once.
Name of the event to bind the callback to.
Function that is called when event is fired. Note the callback is limited to 8 arguments.
Optional
scope: object = ...Object to use as 'this' when the event is fired, defaults to current this.
obj.once('test', function (a, b) {
console.log(a + b);
});
obj.fire('test', 1, 2); // prints 3 to the console
obj.fire('test', 1, 2); // not going to get handled
Remove Script.
True if removed or False if already not in registry.
app.scripts.remove('playerController');
Container for all Scripts that are available to this application. Note that PlayCanvas scripts can access the Script Registry from inside the application with AppBase#scripts.
